Read Model needs Role Definitions ?

Harumpel

Hi there,

I achieved to train a quite capable neural network and used the "Write Model" operator to save it.

Now I created a copy of the process and replaced the neural network training (2 operators: import data & neural net) by the "Read Model" operator.

Now I thought the output would be the same !

Strangely, the "Performance" operator behind the "Apply Model" operator now asks me to "insert apply model operator to add predictions". What is that ??

Kind Regards
Theo

Hi,
did you try to execute the process? I would suggest storing all data files in the repository. Otherwise it isn't ensured, that the meta data transformation is performed correctly. If the process runs fine, there might simply be an problem with the meta data transformation.
Would you be so kind to give me the training as well as the application process and replace the data sources with a generate data operator? I will then be able to trace down this problem.

Greetings,
Sebastian
